Minnesota Schedule M1M

What is Schedule M1M

Minnesota Schedule M1M is a supplemental schedule for the Form M1 individual income tax return. Taxpayers who need to report income additions, subtractions, or adjustments to their federal adjusted gross income must complete and attach Schedule M1M. This form allows you to modify your federally reported income so it aligns with Minnesota tax law.

Schedule M1M must be filed by Minnesota residents and by nonresidents or part-year residents who have income from Minnesota sources. The form and instructions are on the Minnesota Department of Revenue website.
